微处理机控制的话音/数据内插系统

本文介绍了一个用微处理机控制的话音数据内插系统.该系统利用话音内插原理增加载波电路的容量,可以在一个载波电话电路上传输一路话音信号的同时再传输一个50～9600bit/s 的数据信号.该系统由两个终端组成,每一个终端均由一个微处理机控制.微处理机用以进行话音检测和系统的控制.其它部分由硬件构成.所有软件程序均可以固化在EPROM 上.经计算机模拟和硬件电路测试分析,获得了满意的结果.

A Micro-computer Controlled Speech/Data Interpolation System

This paper presents a micro-computer-controlled speech/data interpolation system.The proposed system uses speech interpolation principle to increase the capacities of transmission facilities.As a result of that,a 50-9600bit/s data signal can be tansmitted in-a carrier channel during silence durations of telephone conver- sation. The proposed system is composed of two terminals,each one being controlled by a micro-computer,which is used to detect the presence of speech signals and control the system operation.The other parts are constructed with the hardware circuits.All software programs are fixed in the EPROMS. The computer simulation results and the hardware circuit experiments in the laboratory are satisfactory.
